Meeting with Blue and Gold Officer?

I have to schedule a meeting with my blue and gold officer next week. She said she comes to my house, which i thought was unusual, is it? I mean because i will need to have my brothers and sisters out of the house and clean the house up obviously. Also, what kind of questions should I expect. Do they look for certain "things" at your house as well, like make sure it is clean and they will note it is dirty or unconventional things like that?

It is not unusual for a BGO to meet with candidates at their homes providing it is acceptable and convenient with the parents. By the same token, I have met with candidates at a restaurant, library, school, church, etc, because it was mutually convenient and expeditious. If meeting with your BGO at your home is not acceptable, you should so advise the BGO.
What questions should you expect? What attracted you to NAVY? What do you expect to accomplish via NAVY? Do you intend to be career NAVY/USMC? What do you know about NAVY? What have you accomplished in your school and your community and how does that translate to your leadership potential? And many more similar questions.

The one piece of advice -- dress like you would if you were meeting at the BGO's house or some other location. That means shoes and socks, pressed pants (or whatever the equivalent is in your area), collared shirt (can be polo), etc. Don't wear ratty sweat and have bare feet -- as one of my interviewees once did.

I realize that it's tradition/custom for some not to wear their shoes in their homes. However, I recommend that, this one time, you wear shoes and don't ask the BGO to remove his/hers.

Why? The BGO might not expect to have to remove shoes and might have holes in socks or, especially in the case of female BGOs in the summer, not wear socks. That leaves the BGO feeling very uncomfortable -- i.e., walking around in bare feet, which isn't a good start.

As for you, if you're not wearing shoes and the BGO is, the BGO is feeling uncomfortable about "violating" your house rules.

It's NOT a huge issue but, for an hour of your life, wear shoes in your house and allow the BGO to do the same. JMO.

and please, if you have a pet or pets, put them somewhere safe and out of the way of your interview.
It is really awkward having your dog or cat jump up on or lick the BGO. In one home I felt something rubbing my foot and looked down to find a rabbit. I am a pet lover, but....
